Suspended Solids Turbidity Monitor CRIUS® SoliSense
Whatever level of suspended solids or turbidity monitoring you want to measure, the CRIUS®SoliSense (Pat pending) is the solution. A sophisticated sensor that ranges from 0.02 NTU (FTU) to 8% solids, this turbidimeter, suspended solids monitor, is the solution, and is unique in its ability to measure from NTU to percent solids in one sensor. Suitable for potable water monitoring, filter monitoring, mixed liquor suspended solids monitoring, return activated sludge, centrate monitoring, filtrate monitoring, sludge, and many more applications where a traditional turbidimeter or suspended solids analyzer would be used.
The SoliSense turbidity meter or turbidimter/suspended solids analyser is suitable for dip monitoring, in line monitoring and flow through monitoring. For an at line turbidimeter, please click here, Turbidimeters.
Turbidity Meter Suspended Solids Analyser Benefits
- Designed for Industry as well as Waste WTW suspended solids monitoring
- Successful where other suspended solids monitor instruments fail
- Process monitoring and control in real-time with PID control
- Self-cleaning suspended solids meter with a robust design reduces maintenance costs
- Automatic self-compensation for turbidimeter sensor fouling
- Range of process control PID algorithms for suspended solids analyser control
- Proven to be accurate and reliable where other turbidity monitors have failed
- Datalogging and Remote Internet Access with text alarms
- Bubble compensation for the turbidimeters and suspended solids meter measurements
Turbidity Meter Suspended Solids Principle of Operation (Pat Pending)
The CRIUS® SoliSense Turbidity meter Suspended Solids analyser instrument uses two light emitters and four detectors arranged around a circular aperture. This eliminates interference from extraneous light sources and compensates for detector soiling and the ageing of the optical modules. The arrangement of this 8 beam technology allows measurement of the light transmitted, scattered or reflected by a medium. This allows for the most precise measurement of turbidity suspended solids in a liquid from 0.02 NTU up to 8% solids! For suspended solids monitors for suspended solids greater than 8% please see our dry solids analyser.
The CRIUS® SoliSense turbidity suspended solids meter is designed for any application from 0.02 NTU to 8% solids but is particularly useful for online turbidity meter applications where the concentration of particulate in a fluid is not known or where it varies, such as:
- Inlet monitoring (turbidity 1-4,000 NTU)
- Effluent monitoring (suspended solids 1-1,000 mg/l)
- Distribution monitoring (turbidity 1-100 NTU)
- Hydrant monitoring (turbidity 1-20,000 NTU)
- Fire hydrant monitoring (turbidity 1-20,000 NTU)
Traditional monitoring applications where the CRIUS® SoliSense is particularly suited:
- RAS (Return Activated Sludge)
- MLSS (Mixed Liquor Suspended Solids)
- WAS (Waste Activated Sludge)
- Thickened sludge
- Centrate
- Filtrate
- Effluent
- Inlet
- Filter
The CRIUS® SoliSense is unique in that it offers an online turbidity meter with bubble conpensation and automatic sensor fouling compensation with an automatic cleaning function for low turbidity all the way up to 8% suspended solids in the one probe! This turbidmeter, suspended solids analyser is unique (patent pending) in its ability to measure this range of solids in water in the single sensor.
The SoliSense is both autoranging and user selectable, so from the single suspended solids sensor you can choose, for example 0-2 NTU, 0-2000mg/l, or 0-8%. The top and the bottom end of the range are completely independent, so between 0 NTU or 8% suspended solids the user is completely free to choose the range that they are interested in.
